Evaluating whether someone's behavior is praiseworthy or blameworthy is a fundamental human trait. A seminal study by Hamlin and colleagues in 2007 suggested that the ability to form social evaluations based on third-party interactions emerges within the first year of life: infants preferred a character who helped, over hindered, another who tried but failed to climb a hill. This sparked a new line of inquiry into the origins of social evaluations; however, replication attempts have yielded mixed results.

The human cerebral cortex shows hemispheric asymmetry, yet the microstructural basis of this asymmetry remains incompletely understood. Here, we probe layer-specific microstructural asymmetry using one post-mortem male brain. Overall, anterior and posterior regions show leftward and rightward asymmetry respectively, but this pattern varies across cortical layers.

Knowledge about personally familiar people and places is extremely rich and varied, involving pieces of semantic information connected in unpredictable ways through past autobiographical memories. In this work, we investigate whether we can capture brain processing of personally familiar people and places using subject-specific memories, after transforming them into vectorial semantic representations using language models. First, we asked participants to provide us with the names of the closest people and places in their lives.

Complex macro-scale patterns of brain activity that emerge during periods of wakeful rest provide insight into the organisation of neural function, how these differentiate individuals based on their traits, and the neural basis of different types of self-generated thoughts. Although brain activity during wakeful rest is valuable for understanding important features of human cognition, its unconstrained nature makes it difficult to disentangle neural features related to personality traits from those related to the thoughts occurring at rest. Our study builds on recent perspectives from work on ongoing conscious thought that highlight the interactions between three brain networks - ventral and dorsal attention networks, as well as the default mode network.

Article Synopsis
  • * To study how networks adjust to local disturbances, researchers applied transcranial magnetic stimulation (TMS) to the IPL while participants engaged in different cognitive tasks and also at rest.
  • * Results showed that while TMS reduced network activity during tasks, it enhanced interactions among networks during rest, demonstrating the brain's short-term adaptive plasticity in response to inhibiting specific network nodes.

This study investigates the proposed mechanism of mindfulness, its impact on body awareness and interoception, and its potential benefits for mental and physical health. Using psychophysical assessments, we compared 31 expert meditators with 33 matched controls (non-meditators who engage in regular reading, more than 5 h per week) in terms of somatosensory accuracy with a somatosensory signal detection task (SSDT) and interoceptive sensibility via self-report measures. We hypothesized that meditators would demonstrate superior somatosensory accuracy, indicative of heightened body awareness, potentially linked to increased alpha modulation in the somatosensory cortex, as observed via electroencephalography (EEG).

The cerebellum plays important roles in motor, cognitive, and emotional behaviors. Previous cerebellar coordinate-based meta-analyses and mappings have attributed different behaviors to cerebellar subareas, but an accurate behavioral topography is lacking. Here, we show overrepresentation of superior activation foci, which may be exacerbated by historical cerebellar neglect.

The long-standing hypothesis that autism is linked to changes in the visual magnocellular system of the human brain has never been directly examined due to technological constraints. Here, we used a recently developed 7-Tesla functional MRI (fMRI) approach to investigate this hypothesis within the visual sensory thalamus (lateral geniculate nucleus, LGN). The LGN is a crucial component of the primary visual pathway.

Article Synopsis
  • Humans can categorize visual information into specific groups, with previous fMRI studies highlighting how the brain distinguishes between broad categories (like animate vs. inanimate) and individual objects.
  • Recent research used fMRI coupled with multiple examples of 48 different mammals to examine this further, aiming to clarify the distinctions between fine-grained and coarse-scale representations.
  • The findings suggest fMRI primarily captures visual-specific and general category information, but it can also identify subtle differences between individual objects, challenging earlier assumptions about the level of detail provided by fMRI data.

Autism spectrum disorder (ASD) is a neurodevelopmental condition associated with altered resting-state brain function. An increased excitation-inhibition (E/I) ratio is discussed as a potential pathomechanism but in-vivo evidence of disturbed neurotransmission underlying these functional alterations remains scarce. We compared rs-fMRI local activity (LCOR) between ASD (N=405, N=395) and neurotypical controls (N=473, N=474) in two independent cohorts (ABIDE1 and ABIDE2).

  • - White matter hyperintensities indicate damage in the brain's white matter, which can lead to brain shrinkage and is linked to dementia; a study of over 51,000 people found that larger volumes of these hyperintensities correspond to thinner brain cortex.
  • - Researchers identified 20 significant genetic loci related to white matter hyperintensities that affect genes involved in brain cell types known to support vascular health and neuronal function; some of these genes play roles in processes like axonal structure and transport within the brain.
  • - The genetic traits tied to white matter issues were linked to cardiovascular health, neurodegeneration markers, and poorer cognitive performance, with a polygenic risk score effectively predicting dementia risk in a separate large

Background: Epidemiological research has failed to confirm laterality of lesion site as a neurobiological source of post-stroke psychopathology. However, acquired communication disorders have proved to be a key risk factor for depression, apart from established parameters such as pre-stroke psychopathology and physical immobility.

Objectives: The present work examines a new predictor of post-stroke psychopathology: psychological flexibility.

Magnetoencephalography and electroencephalography (M/EEG) seed-based connectivity analysis requires the extraction of measures from regions of interest (ROI). M/EEG ROI-derived source activity can be treated in different ways. It is possible, for instance, to average each ROI's time series prior to calculating connectivity measures.

Notwithstanding advances in computational models of neuromodulation, there are mismatches between simulated and experimental activation thresholds. Transcranial Magnetic Stimulation (TMS) of the primary motor cortex generates motor evoked potentials (MEPs). At the threshold of MEP generation, whole-head models predict macroscopic (at millimeter scale) electric fields (50-70 V/m) which are considerably below conventionally simulated cortical neuron thresholds (200-300 V/m).

The wide array of cognitive functions associated with the hippocampus is supported through interactions with the cerebral cortex. However, most of the direct cortical input to the hippocampus originates in the entorhinal cortex, forming the hippocampal-entorhinal system. In humans, the role of the entorhinal cortex in mediating hippocampal-cortical interactions remains unknown.

  • The spinal cord plays a crucial role in brain-body communication, but traditional noninvasive recording methods in humans face significant challenges.
  • Researchers developed a new electrophysiological approach that uses high-density multichannel spinal recordings and advanced spatial-filtering analyses, allowing for detailed timing and sensitivity in spinal cord response assessments.
  • This method was further expanded to include simultaneous recordings from peripheral, spinal, and cortical areas, providing evidence that integrative processing starts in the spinal cord, and was applied to study nociceptive responses during pain stimulation, paving the way for better understanding of brain-body interactions in health and disease.

Previous studies have found that threatening stimuli are more readily perceived and more intensely experienced when presented during cardiac systole compared with diastole. Also, threatening stimuli are judged as physically closer than neutral ones. In a pre-registered study, we tested these effects and their interaction using a naturalistic (interactive and three-dimensional) experimental design in immersive virtual reality: we briefly displayed threatening and non-threatening animals (four each) at varying distances (1.

The human brain tracks regularities in the environment and extrapolates these to predict future events. Prior work on music cognition suggests that low-frequency (1-8 Hz) brain activity encodes melodic predictions beyond the stimulus acoustics. Building on this work, we aimed to disentangle the frequency-specific neural dynamics linked to melodic prediction uncertainty (modelled as entropy) and prediction error (modelled as surprisal) for temporal (note onset) and content (note pitch) information.

Background: The subgenual Anterior Cingulate Cortex (sgACC), as a part of the Anterior Cingulate Cortex and the limbic system plays a crucial role in mood regulation. Previous structural and functional brain imaging studies of the sgACC have revealed alterations of Gray Matter (GM) volumes and Blood Oxygenation Level Dependent signals (BOLD) in patients with Major Depressive Disorder (MDD) and Bipolar Disorder (BD), suggesting potential biomarker traits for affective disorders.

Method: In this study we investigated the gray matter volume of the sgACC in 3 different patient groups: 40 MDD patients, of which 20 were medicated (MDDm) and 20 were unmedicated (MDDu), and 21 medicated BD patients, and compared them with 23 healthy volunteers.

  • - The study investigates how brain region degeneration relates to social cognition (SC) and executive functions (EF) deficits in patients with behavioral variant frontotemporal dementia (bvFTD), involving 103 participants from Germany.
  • - It reveals that performance in understanding social cues (using the Reading the Mind in the Eyes Test) correlates mostly with gray matter volume and cortical thickness in the temporal and insular areas, while EF performance is linked to prefrontal regions.
  • - The findings highlight that there is some overlap in the brain regions associated with both SC and EF, particularly in the insula and the dorsolateral prefrontal cortex, and these patterns are clearer when considering both cognitive domains together.

Humans build mental models of the world and utilize them for various cognitive tasks. The exact form of cognitive maps is not fully understood, especially for novel and complex environments beyond the flat Euclidean environment. To address this gap, we investigated -a critical process underlying cognitive mapping-and spatial-memory capacity on the spherical (non-Euclidean) and planar (Euclidean) environments in young healthy adults ( = 20) using immersive virtual reality.
